POLYCAB MEDIUM VOLTAGE HIGH TENSION CABLE CONFORMING TO ICEA S-93-639

Polycab Medium Voltage High Tension cables ofvoltage graderanging from 5 kV to 36 kVare suitable to use in conduits, ducts, troughs, trays, direct burial in wet and dry conditions for power supply to wide networks. These cables are available with EPR insulation (XLPE insulation available on demand) having temperature rating of 105°C.

These cables are halogen free flame retardant in characteristic and provide continuous load and Extra- protection from short circuit and Fire.

Technical advantages:

  • Conductor: High conductivity annealed plain stranded compacted aluminium / copper conductor produced in- house from state-of-the art machine.
  • Conductor Screen: an extruded layer of cross-linkable semi conducting compound to eliminate sharp points on conductor surface and also nullifies chance of electric discharge at interface between conductor / insulation
  • Insulation: In-house developed high insulation resistance Ethylene Propylene Rubber thermoset insulation compound. (XLPE insulation available on demand)
  • Non-metallic Insulation Screen: an extruded layer of cross-linkable semi conducting compound, applied in triple extrusion with conductor screen and insulation extrusion, to eliminate micro voids and curing resulting longer life of cables
  • Metallic Screen: a helically applied copper tape screen to carry fault current (corrugated/round wire copper screen is optional)
  • Laying Up: in case of 3 core Cable, insulated cores laid up together with in-house developed fillers to maintain circularity of cable and optional ground wire for earthing purpose
  • Wrapping tape: in case of 3 core cable, a wrapping tape applied over laid up core assembly
  • Optional Armour: to give mechanical protection and also acts as return path for earth fault current
  • Outer Sheath: In-house developed thermoplastic compound having low emission of smoke and corrosive gases when exposed to fire.
